DCMT 11T308 AH725 ISO turning insert (Turning) — PVD-coated carbide, 0.8 mm radius, Tungaloy

The DCMT11T308 AH725 is an ISO-standard indexable turning insert designed for general external and internal turning, offering a universal, fracture-resistant grade for applications involving Stahl and rostfreier Stahl.

• PVD-coated carbide for consistent edge life
• Universal AH725 grade for Stahl and rostfreier Stahl
• 0.8 mm corner radius for versatile finishing
• ISO DCMT shape with cylindrical hole and countersink

Predictable cutting performance for mixed materials

The insert delivers reliable cutting behaviour thanks to its PVD-coated carbide substrate and the AH725 grade, which is engineered for universal use across Stahl and rostfreier Stahl. This combination supports stable chip formation and reduces unpredictable edge failure, improving overall process security. For operations that shift between different workpiece materials or require smaller tooling, the consistent wear behaviour minimises the need for frequent grade changes, enhancing productivity on batch or mixed-production runs.

Compatibility and quick changeover for efficient tooling

Designed to the ISO geometry, the indexable plate ensures fast, repeatable mounting in standard DCMT holders. The cylindrical hole with a single-sided countersink (40°–60°) and the plate thickness of 3.97 mm contribute to secure clamping and repeatable seating, shortening setup time and reducing rework. Clearances and tolerances matched to the ISO series lower the risk of misalignment, while the robust form factor supports both external and internal turning tasks with reliable seating and tool life.

Improved uptime through controlled chip shaping and edge geometry

The integrated one-sided chipbreaker and the 0.8 mm corner radius reduce vibration and support chip control across finishing and light turning passes. The modest corner radius gives a balance between strength and surface finish, enabling consistent dimensional results with fewer insert changes. By selecting a universal AH725 sort, tool inventory is simplified and changeover frequency is reduced, contributing to measurable savings in setup time and tooling logistics.

Consistent surface quality and process stability

The rhombic plate form with a 55° included angle and a 7° relief angle provides steady cutting forces and favourable approach geometry for finishing operations. The plate geometry supports predictable tool deflection and surface integrity, which is particularly important in series production where repeatability matters. Backed by the Tungaloy design philosophy, the insert combines practical geometry with modern coating technology to deliver consistent results on a wide range of turning applications.

FAQ

What materials is this insert suitable for?
The DCMT11T308 AH725 insert is specified for machining Stahl and rostfreier Stahl, offering a universal performance profile for mixed-material production.

Which holder types are compatible with this plate?
Compatibility is determined by the DCMT form, the 7° relief, plate thickness (3.97 mm) and the ISO dimensions; matching DCMT ISO holders and clamping screws will secure the plate correctly.

How does the AH725 grade affect tool life?
The AH725 PVD-coated grade provides stable wear characteristics and fracture resistance, which supports longer edge life and improved process security in varying machining conditions.

Can the insert be used for finishing and light turning?
Yes; the 0.8 mm corner radius and 55° rhombic geometry are suited to finishing and light turning where surface quality and dimensional repeatability are required.

What chip control can be expected with this geometry?
The one-sided chipbreaker is tuned to produce controllable chips in common turning operations, reducing the risk of chip entanglement and improving surface consistency.
